Selected Orange SIM and activated with plan that has data in UK while visiting. Voice and text work fine but cannot get a 3G connection. Have verified setup is set so data connection is on and set to 3g for cellular. Anything else anyone can suggest.

You may need to setup the APN for Orange, or use the HTC connection application. Either download (via WiFi) and use the application, or head to settings => mobile network (or cellular) => and at bottom tap edit apn. Once there input these values:

APN: orangeinternet
Username: Orange
Password: Multimedia

Now you should have access to their data network.

NOTE: You will need to revert your settings upon returning to your country.

Do you know what 3G frequencies Orange uses in the UK? I've used Orange in France and they use UMTS 900 / 2100 MHz for 3G. I would think that they use the same frequencies in the UK for 3G, but I don't know for sure. Does the Verizon Trophy support UMTS 900 / 2100 MHz for 3G?

On return to US - switched to CDMA - used HTC Connection software and selected Verizon. Data didnt work. Did a power reset of the phone and everything worked just fine.

So I now know the key is power reset. The data on Orange Pay as you go worked out just great with the chaos at heathrow airport yesterday. Was able to amuse myself for 5 hours.

At least we have a working world phone now....

I do now want a Nokia 900 phone - the only thing that I dont like about the trophy is the Camera.

I wonder if using a non-Verizon SIM whole overseas helps? If the phone locks on a tower abroad w/ VZW SIM, that prompts need for factory reset. If you use local SIM overseas, does that make a difference? It seems like it might, if all you needed was a POWER reset rather than a FACTORY reset. (of course I moved on from Trophy a while back, but I am a scientist - I need to learn & understand. Its how I roll.)

Palandri, any thoughts?

Not really, I've never had a dual band CDMA/GSM phone, only GSM. Didn't the Verizon get a recent update to fix that? That's all I can think of.

I doubt the network provider for the SIM card has anything to do with the need to power reset the phone. My thought is that the settings are changed but it requires a power startup to take those into account. There is no indication when chnaging these settings that this is the case however the fact that both CDMA -> GSM and the GSM->CDMA on return to US required power reset to make the 3g data connections indicates this is probably the case.

I think the 8107 + radio updates along with the HTC connection software updates were required but at least they work now.
